Can i use lwm2m library of iot sdk used over UART instead of 6lowpan ble interface? Please let me know how i can use this iot sdk over UART instead of 6lowpan? i want to use gsm module on the place of raspberry pi border router..

Question

I want to communicate with lwm2m server using gsm module and nrf52832 as lwm2m client. i installed lwm2m demo server over linux machine.

Hi Abhishek, 
 The current implementation in our IoT SDK doesn't have the IP stack running on the nRF52. It's on the gateway as shown here. 
 I assume you don't use BLE for this communication at all ? I got a suggestion from our developer with the following diagram: 
 If you don't use BLE 6LowPAN then only the green part is needed. We suggest you to implement the IP stack driver with network interface, for example lwIP in our older IoT SDK: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.iotsdk.v0.9.0/iot_sdk_user_guides_lwip_stack.html?cp=7_4_4_12 The network interface here would be useful: https://github.com/ARMmbed/mbed-os/tree/master/features/lwipstack 
 Please be aware that this is not something we can support and make an example for you. And you would need to implement based on what we have. And we believe there should be someone else already implemented something similar. 
 For example: https://github.com/ARMmbed/mbed-os-example-cellular 
 https://github.com/zephyrproject-rtos/zephyr/pull/6344
